摘要： An illumination device is provided for controlling a color temperature of light irradiated from a light source having a plurality of light-emitting elements of different light colors. A control setting module provides a control signal associated with a desired color temperature for the irradiated light. A light quantity determination circuit determines light quantities for each of the light-emitting elements based on a relationship between the control signal from the control setting module and an inverse color temperature. A plurality of driver circuits provide driver signals to the light-emitting elements corresponding to the determined light quantities. In this manner the color temperature for light irradiated from the light source coincides with the desired color temperature.

摘要： An LED driving circuit includes a dimming control value detection circuit adapted to detect a dimming control value which indicates a ratio of the actual current to be supplied from a current source to the driving circuit during a predetermined time period with respect to a rated current. A control circuit is adapted to regulate the amount of current supplied to one or more LEDs during the predetermined time period to either of the dimming control value squared or the dimming control value cubed times the rated current. The characteristic of light output to the amount of current supplied from the current source during a predetermined time period is therefore made approximate to that of an incandescent bulb.

摘要： An OLED driver possesses a square-wave voltage source, a controller and a detector. In accordance with first control, the source generates square-wave voltage and applies the voltage across at least one organic electroluminescence element to drive the element. The controller controls the source in accordance with the first control. The detector detects equivalent capacitance inherent in the element. The controller also judges whether or not the element is normal based on the equivalent capacitance. If the element is normal, the controller operates in accordance with the first control. If the element is not normal, the controller operates in accordance with predetermined second control for the element which is not normal.

摘要： A lighting apparatus of high intensity discharge lamp comprises a DC power source, a series connection of a first and a second transistors; a series connection of a first and a second capacitors connected in parallel with the series connection of the transistors; a series connection including at least an inductor and a discharge lamp connected between a connection point of the transistors and another connection point of the capacitors, and a control circuit for switching on and off of the transistors so as to supply electric power to the discharge lamp. A voltage of the first capacitor is set to be higher than that of the second capacitor corresponding to the capacitances of the first and second capacitors. Thus, the pulse height in negative or positive phase of the rectangular alternating voltage applied to the discharge lamp can be increased without increasing the output voltage from the DC power source.
